Radiation effects for STM32H755

Our product is a space device and as a result, we've had to recently do some radiation testing of the device. In particular, focused on the STM32H755 processor that runs the board.

I'm looking for any papers/references/app_notes, anything, that can help me to gather details about how the processor performs in a radiation environment.

And yes, I realize this is not a rad-hard or rad-tolerant processor. 8-)

Thanks.

You have already answered it yourself: the STM32 are generally and the STM32H755 specifically not rad-hardened, so there are neither investigation reports nor papers or appnotes.

I realize after doing a google search, there are a small number of "others" using the STM32 MPU in a space environment. Those of us doing this are definitely pushing the boundary. But, that's what innovation is about.

Thanks for confirming what I suspected.
